Area Forecast Discussion
National Weather Service Burlington VT
306 AM EDT Fri Sep 11 2020

.SYNOPSIS...
High pressure builds into the region today into Saturday with 
skies trending mainly clear and seasonably cool temperatures. 
Showery weather arrives for Sunday as another front sweeps into 
the region, followed by a return to seasonable and mainly dry 
weather for much of next week with mild afternoon highs and cool
overnight lows.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 306 AM EDT Friday...Cloudy skies this morning will trend 
mainly clear by later today into this evening as high pressure 
builds east from the Great Lakes. Outside some patchy morning 
drizzle in a few spots, dry weather is expected. Highs today 
reflect cool nature of Canadian airmass advecting into the 
region on modest northerly flow - mainly 60s. 

Clear skies and light winds will then be the rule tonight as center 
of the high bridges atop the region. Ideal radiational effects 
expected with lows bottoming out generally in the 35 to 45 range, 
milder near Lake Champlain. Probabilities of slightly lower readings 
highest in the Northeast Kingdom where a Frost Advisory has been 
posted for favored valleys/hollows of Essex and Caledonia Counties.

A beautiful day remains on tap for Saturday as the surface high 
remains atop the region. Some filtered high clouds may arrive late 
from the west, but largely sunny skies are expected as highs top out 
in the upper 60s/lower 70s under light southerly return flow.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 306 AM EDT Friday...The high pressure responsible for our
nicer weather will shift eastward over the Atlantic Ocean 
Saturday night which will moisture to begin streaming back into 
the region. Looking at the NAM and GFS guidance for Saturday 
night, decent moisture advection and warmer air filtering into 
the 850 mb and 925 mb levels should help increase cloud cover 
across northern New York and western Vermont through the 
overnight hours. Eastern Vermont will likely be clearer through 
much of the overnight period which will allow them to be quite a
bit colder than further west. Overnight lows Saturday night 
will range from the mid 40s to mid 50s with the coldest 
temperatures occurring across eastern Vermont. Rainfall ahead of
an approaching cold front will move into the St. Lawrence 
Valley Saturday morning after 8 AM. All of the latest 00Z 
guidance continues to delay the onset of rainfall across the 
North Country which is attributed to the upper level low over 
the Four Corners region weakening into an upper wave. 
Nevertheless, widespread rain showers will be seen throughout 
the region during the daylight hours on Sunday with most places 
seeing a quarter of an inch to a half of an inch of rainfall. 
The only exception to this will be across far southeastern 
Vermont where rainfall amounts are expected to be less than 
0.15" as they will be well removed from the best forcing.

We continue to look at strong gradient winds developing Sunday
morning and continuing through the afternoon hours across the
northern Champlain Valley. Unlike the wind event last week, the
strongest winds this time will likely be tied to Lake Champlain with
wind gusts in the 35 to 45 mph. As you head away from the lake, wind
gusts in the 20 to 30 mph range look more likely. The winds should
peak during the early afternoon hours as mixing within the marine
boundary layer helps to mix down some stronger winds from around
1500 ft. Once the sun sets, any mixing will cease and winds will
slowly relax as the pressure gradient begins to weaken. Given a
strong southwest low level jet across the Adirondacks and Green
Mountains, we will likely see rain shadowing across portions of the
Champlain and St. Lawrence Valleys which could yield slightly lower
rainfall amounts than previously mentioned.

A few lingering showers will likely continue overnight Sunday into
early Monday morning as the upper level trough axis passes through.
Any additional rainfall will be light with just a few hundreths of
an inch of rain expected. Overnight lows will once again be on the
warm side as we should see mostly cloudy skies persist through the
overnight hours.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 306 AM EDT Friday...Tranquil weather is in store for next
week as we see high pressure settle across the North Country. 
Noticeably colder temperatures will be seen on Monday and 
Tuesday with highs only climbing into the lower to mid 60s with 
lows in the mid 30s to mid 40s. Patchy frost is expected across 
northeastern Vermont and portions of the northern Adirondacks 
once again Monday night and Tuesday night. We will see a warming
trend on Wednesday and Thursday with our temperatures returning
to near normal values but another cold front on Thursday will 
bring below normal temperatures to the region to end the 
upcoming week. There could be a few rain showers with the front 
on Thursday but the surface low will once again track well north
of the international border which will leave us on the tail end
of the cold front.

&&

.AVIATION /07Z FRIDAY THROUGH TUESDAY/...
Through 06Z Saturday...Frontal boundary continues to pull south
and away from the area. Lingering MVFR/brief IFR expected through
12Z in moist post-frontal northerly flow with patchy drizzle
possible. Quick improvement to VFR is expected at all terminals
in the 12-18Z time frame, with SKC conditions after 21Z as
surface high pressure builds into the region. Winds northerly 
generally from 6-12 kts, occasionally gusty into the 14-18 kt 
range this afternoon before abating to near calm after 00Z 
Saturday.

Outlook...

Saturday: VFR. Patchy BR.
Saturday Night: VFR. Slight chance SHRA.
Sunday: Mainly VFR, with areas MVFR possible. Windy with gusts to
30 kt. Likely SHRA.
Sunday Night: MVFR/IFR conditions possible. Chance SHRA.
Monday: Mainly VFR, with areas MVFR possible. NO SIG WX.
Monday Night: VFR. NO SIG WX.
Tuesday: VFR. NO SIG WX.
